Ultraviolet isn't illegal. Allowing someone else to have your UV code is probably against their T&Cs, though.
The law is in the process of changing so that it will no longer be illegal for people to backup their films. I have a backup of every film that I have purchased, regardless of if it comes with a digital copy or not, so that I can watch the film on any of my devices.
I thought it was legal for everyone to have one backup copy of the stuff they owned anyway...? Even though it can be difficult for the average bod on the street to do...
Or do you mean they're going to be making that illegal?
